To aZZ .ic/ma 1f may concern:

Be it known that l, DAVID S. KENNEDY, of the borough of Brooklyn, county of Kings, and State ot New York, have invented a new and useful Improvement. in Line-Casting Machines, of which the following is a specification.

My invention has reference to line-casting machines such as represented in Letters Patent of the United States No. 436,532 and kindred machines, wherein a movable melting pot is provided with a mouth arranged to close against a slotted mold, and with an internal plunger for delivering metal through the mouth into the mold. In the operation vat these machines it'is important, for various reasons, to maintain the level of he molten type-metal at a uniform height. To this end sslid metal is suppliedito the pot from time to time by the operator.

The object of my invention is to call the attention oit the operator to the fact that the metal is falling below the proper level and should be replenished.

To this end it consists in an alarm mechanism of novel const-ruction, comprising a vertically guided rodcarried by the pot, provided at its lower end witlra float to rest on the molten metal, and at its upper end with a latch adapted toengage and actuate a bell-striker mounted on a iixed support as the pct moves to and fro whenever the metal therein is below the proper level.

The draw'ings'are limited to those parts of theiuachine immediately associated with my invention. lt is to be understood that all other parts may be of any ordinary or suitable construction.

In the drawings: wFigure l is a view in vertical section through the machine, showing` the metal pot and adjacent pzirts. Fig. 2 is a similar elevation of the alarm mechanism.

Referring to the drawings, A represents thaler machine, having a horizontal motion to and from the mold. B represents the body of molten metal therein. C 1s a' vertical rod guided 1n bearings on shelhlout it may be of carbon or of any Specification of Letters Patent.

other material adapted to oat on the molten metal without being affected thereby.

F is a pendent dog or latch connected to the upper end of the rod C by a horizontal ivot f', and arranged to swing` freely in a hackward direction from a sto pin f', seated in the side of the rod C, and limiting the 'forward motion of the dog.

G is a bell or gong secured to the side of a supporting arm H, which is in turn secured to the main frame or the machine by bolts, l.

K is a gravitating' strikerorl hammer ar-l ranged to act on the bell G, supported near its upper end on a pivot screw t, seated in the arm H. The upper end ofthe striker'K has aA lateral projection arranged inl the same' vertical plane as the dog F.

The operation of the parts is as follows: As the pot moves to and fro the rod C and the dog F are carried with it. When the vmetal is at the proper height in the pot the iioat E sustains the rod C and the dog F at such height that the dog will pass to and fro above the upper end of the striker K without acting thereon, and the bell will remain silent. When, however, the metal falls below the proper level thr lower end of the dog F will stand in such position that when the ,pot moves rearward the lower end of the dog` will act upon the striker. and, depressing its upper end, lift the striker clear of the bell until, linally, the dog passes over the end of the striker, releasing the same and permitting it to fall upon and sound the 1nell. As the pot .',noves forward the dog, swinging about its pivot, will' pass idly over the end of the striker and fall into operative position. in front of the same. The parts will continue to sound t1ie'hell at each retreat of the pot until the addition of metal to the pot= raises the metal therein to the proper level, whereupon the loat will again lift the dog to its inoperative position.

It will be manifest that the form of the dog and g'eiides may be modified within the range of mechanical skill. I prefer to seat the rod C in grooves in-t-he side of the support D and .to confine it therein by gravitating` pivoted latches c, as shown. The rod may be released for removal by turning the latches c upward and backward.

The bell-sustaining arm or bracket H and the supporting or guiding arm D are so designed that they may be applied to commercial Mergenthaler machines now in eirtensive use. In other Words, these parts as shown and described constitute in themselves a. complete commercial mechanism adapted to be sold as an article' of commerce for application to existing machines.

Having described my invention, what I claim'is:

l. r)The fixed bracket H, having the bell and the striker thereon, in combination with the support D attached to the movable pot A, the vertically guided rod C, the float E attached thereto, and the dog F pivoted to said rod. I

2. n a line-casting machine, the combina v tion of a bell and a movable striker, with a '1a movable ot and the vertically guided .rojd carried tiereby, said rod provided with a Heat and a striker actuating device arranged to act by direct Contact upon the striker; whereby the movement of the pot eiiects the 20 movement of the striker and rings the bell.

In testimony whereof I hereunto set my hand this fifth day of April, 1910, in the presence of tWo attesting Witnesses.
